Relay Specifications:
- 20A/12V DC NO contact
- 10A/12V DC NC contact
Features:
- Adjustable timing: 0 to 150 seconds (adjusted by trimmer)
- LED indication for activated relay
Important Notes:
- The timer will not function if the power supply is below 10V.
- Setting the minimal time may cause the relay to click upon powering on (not recommended).
- The output does not have voltage; a separate power supply is needed for the load (see diagram).
- For loads exceeding 20A, use a separate powerful relay after the timer.
Principle of Operation:
- When the power is on, the delay time starts, and the LED diode lights up.
- Once the set time elapses, the relay activates, closing the output contact until the power is cut off.
- Restarting the power supply resets the cycle.
Application Example:
- The timer can be used for delaying the activation of car lights. When the ignition starts, the timer will wait (0-150 seconds) before turning on the front lights to conserve the car battery. When the ignition is turned off, the lights will immediately deactivate. The timer requires a 12V input from the contact key, with the output wired to the front light switch.
Important:
- The output does not provide 12V power; it only opens and closes the circuit. You need to obtain power from the car battery.
